Fat Points in a Woman's Life

The Freshman 15 critical age: 18

By now, most women have matured into their adult body-and if it's a healthy one, it's the target size they should maintain for life.

Eat smarter: Weight gain often occurs at this point because Mom isn't making the salads anymore. Parents should stress healthy eating and encourage their daughters to deal with emotions by talking with a friend-instead of turning to food for solace.

Activity Rx: Encourage kids to take advantage of college sports facilities and to make exercise part of their routine.

Insider's tip: Teach your daughter that maintaining this weight requires trade-offs. She can't say no to Sunday night pizza? Fine. Balance the extra calories by walking to class all week instead of riding the bus.
